LP1929839 Load Shared Bucket text error

Changes the title of the Load Shared Bucket pop-up box from "Load Shared
Bucket Bucket by ID" to "Load Shared Bucket by ID".  I decided not to
change it to "Load Shared Bucket by Bucket ID" since "Bucket ID" is
displayed next to the input field.

This affects all 3 types of buckets: item, record and user.
